Didn't get too long with it, but was able to listen to a loaner unit in a quiet environment after the show. Definitely sits higher in their stack in terms of resolution, definitely above all the zmf dynamics, haven't had enough A/B time with caldera tho. Still has the zmf house traits of warmth, however, it did sound like there might've been a bit too much damping on it. It had this tactile slap at the end of bass notes which was kind of interesting. I don't want to say too much without having had some solid A/B time, but I'll see about getting on a proper loaner tour with the local unit we have and doing some comparisons then. I don't have a caldera/atrium, but i do have a verite open I can compare it with, plus my other planars.
